摘要:php之XML转数组函数的详解
如下所示:
[u]复制代码[/u] 代码如下:
<? /** * xml2array() will convert the given XML text to an array in the XML structure. * Link: http://www.bin-co.com/php/scripts/xml2array/ * Arguments : $contents - The XML text *                 $get_attributes - 1 or 0. If this is 1 the function will get the attributes as well as the tag values - this results in a different array structure in the return value. *                 $priority - Can be 'tag' or 'attribute'. This will change the way the resulting array sturcture. For 'tag', the tags are given more importance. * Return: The parsed XML in an array form. Use print_r() to see the resulting array structure. * Examples: $array =   xml2array(file_get_contents('feed.xml')); *               $array =   xml2array(file_get_contents('feed.xml', 1, 'attribute')); */ function xml2array($contents, $get_attributes=1, $priority = 'tag') {      if(!$contents) return array();      if(!function_exists('xml_parser_create')) {         //print "'xml_parser_create()' function not found!";         return array();      }     //Get the XML parser of PHP - PHP must have this module for the parser to work     $parser = xml_parser_create('');     xml_parser_set_option($parser, XML_OPTION_TARGET_ENCODING, "UTF-8"); # http://minutillo.com/steve/weblog/2004/6/17/php-xml-and-character-encodings-a-tale-of-sadness-rage-and-data-loss     xml_parser_set_option($parser, XML_OPTION_CASE_FOLDING, 0);     xml_parser_set_option($parser, XML_OPTION_SKIP_WHITE, 1);     xml_parse_into_struct($parser, trim($contents), $xml_values);     xml_parser_free($parser);      if(!$xml_values) return;//Hmm...      //Initializations     $xml_array = array();     $parents = array();     $opened_tags = array();     $arr = array();     $current = &$xml_array; //Refference      //Go through the tags.     $repeated_tag_index = array();//Multiple tags with same name will be turned into an array     foreach($xml_values as $data) {          unset($attributes,$value);//Remove existing values, or there will be trouble          //This command will extract these variables into the foreach scope          // tag(string), type(string), level(int), attributes(array).         extract($data);//We could use the array by itself, but this cooler.         $result = array();         $attributes_data = array();          if(isset($value)) {              if($priority == 'tag') $result = $value;              else $result['value'] = $value; //Put the value in a assoc array if we are in the 'Attribute' mode         }         //Set the attributes too.         if(isset($attributes) and $get_attributes) {              foreach($attributes as $attr => $val) {                  if($priority == 'tag') $attributes_data[$attr] = $val;                  else $result['attr'][$attr] = $val; //Set all the attributes in a array called 'attr'             }          }         //See tag status and do the needed.         if($type == "open") {//The starting of the tag '<tag>'             $parent[$level-1] = &$current;              if(!is_array($current) or (!in_array($tag, array_keys($current)))) { //Insert New tag                 $current[$tag] = $result;                  if($attributes_data) $current[$tag.
